Texas BioMed Discovers Class of Antibodies That Block HIV Transmission

Researchers from the San Antonio-based Texas Biomedical Research Institute have discovered a new defense against HIV-1, the virus that causes AIDS. The group of Texas BioMed scientists led by Ruth Ruprecht, M.D., Ph.D., used an animal model to show for the first time that an antibody called Immunoglobulin M (IgM) was effective in preventing infection after mucosal AIDS virus exposure. Only certain body fluids from a person infected with HIV can transmit the virus. Infection occurs after fluids such as blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, or breast milk come in contact with a person's mucous membrane or damaged tissue or is directly injected into the bloodstream using a needle or syringe.
